BUILDING BLOCK OB BRICK.

Specification of Letters Patent.

Patented March 16, 1909.

Application filed June 5,` 1908. Serial No. 436,940.

T o all whom it may concern:

Be it known that 1, EDWARD KAYE, a citizen of the United States, residing at Monaca, in the county of Beaver and State of Penn- Sylvania, have invented certain new and useful Improvements in Building Blocks or B ricks, of which the following is a specification.

rlhis invention has relation to building blocks and relates in particular to building blocks having glass faces in imitation of enameled, vitrified or glazed bricks.

My invention consists in the novel construction, combination and arrangement of parts hereinafter described and claimed and in carrying my invention into effect 1 press a glass facing having a front, a bottom and two ends and preferably form the balance of the building block of suitable cement, concrete, plaster or other plastic material which 1 press, tamp, squeeze or otherwise form to the required size and shape, partly within the space bounded by the bottom and the ends of the glass facing and extending adjacent to such facing a sufficient distance in each direction to form with such facing a building block of the krequired size and shape and then allow the plastic material to set or solid condition.

Details of form, material and process of manufacture will be given hereinafter, reference being had to the accompanying drawing illustrating my invention wherein:

Figure 1 is a perspective view of the glass facing before the addition thereto of the cement or similar filling and backing or body. Fig. 2 is a perspective view of the completed block. Fig. 3 is a vertical trans verse sectional view of a mold for forming the plastic backing or body in and on the facing, the facing and body or backing being shown in the mold. Fig. 4 is a vertical transverse sectional view of a portion of a wall composed of my improved building blocks.

rlhe facing, which is composed of glass or otherl similar vitreous material, is either transparent opaque or translucent and of any suitable or desired color, and is composed of the front 1, the two ends 2, and the bottom 3, being open on top and at the rear as shown. A groove 4 is formed in the facing, this groove extending parallel to the dry so as to assume a hard and i vfront 1, along the bottom and both ends,

and leaving a flange 5, the groove and flange serving in connection with ythe mortar or cement ordinarily used, to bind or secure the building blocks, and particularly the facing thereof, in position in the wall or other part of a structure'in which they are laid. The cross sectional form of groove 4 is prefer-f ably triangular, as this form provides a vertical surface on flange 5 at a right angle to the flat horizontal surface and affords a good holding surface for the cement or mortar in which the building blocks are laid.

lndentations or recesses G are formed in the bottom 3 of the facing, which may extend part way or entirely through the bot tom, and serve to affordfadditional holding points for the cement or mortar, as may be seen by an inspection of Fig. 4 in which the cement or mortar in which the building blocks are laid is designated 7 and entirely fills the grooves 4 and the recesses 6.

The facings 1 are formed in a suitably constructed mold by means fof a glasspress in the ordinary and well known manner such as is commonly followed in pressing other glass articles and which need not therefore be described, and are annealed as is usual in the manufacture of other articles of glass.

The completion of the bricks with their glass facing and cement or other primarily plastic backing is preferably and readily accomplished by placing the facing in a mold 9, of suitable size and form,.as shown in Fig. 3, and then filling in the rmold to the requisite height with the plastic material which is pressed, tamped, squeezed or otherwise treated to render it sufficiently compact and the completed block being, if necessary, al lowed to set and dry to sufficient extent to render it easy to handle, is removed from the mold and may be artificially dried and tem- )ered or otherwise treated in the manner and y the means usually employed in the manufacture of cement or concrete building blocks of the ordinary character.

It will be observed that when the bricks or crushingv strain. I claim:

l. A" building block composed vof" a vitreous I facing, comprising front and end Walls and a bottom, the facing being open' on top' said facing being formed with a groove adjacent to and parallel; Withy onesid-e andy extending l arallel" With botli edges of the front inA corn-` bination with a filling and backing coniposed of plastic material molded into and in thel rear of said' facing' and self adherent thereto.

r 2. A building block composedof a vitreous avoiding fracture l facing coinprisingfront and end Walls and a bottoni-,the facing being open on top in comg binationf With a primarily plastic filling molded into and extending rearwardly from `the fa'oi'ngbe'y'ond the end Walls and bottom i and dried in position therein.

3;V A" building block comprisingla vitreous vfacing having a bottom and end Walls and open" on topv anda molded plastic backing extending between the end Walls and in the rear thereof.

linI testimony whereof' I aHiX ny signature, in presenoeof two Witnesses'.
